Long answer: The server running Piwik does not have FTP enabled by default. It’s normally only active for system administration and larger file transfers. I don’t want to activate FTP on this particular server.

I’ve setup a new Piwik installation on another server. Both, Piwik and the server are configured exactly the same way as for my regular Piwik installation. The error will appear there, too. Currently data is gathered from one of my smaller websites, just to get something into the database.

If you like, you can access this installation for testing purposes, also via FTP. As it’s a testing environment you can also change the configuration the way you want. Please send an email to me in order to get more details. I’m in Germany, so my replies might be delayed a bit.

[li] Changing the Suhosin setting of suhosin.get.max_value_length to 2048 will solve the problem. Unfortunately this workaround can’t be applied if you’re on a shared hosting platform.
[/li][li] The fixed pdf.js provided in trunk has also solved the problem, without changing the Suhosin settings.
